Abstract:
The study of the planet-debris disk connection can shed light on the
formation and evolution of planetary systems and may help "predict"
the presence of planets around stars with certain disk
characteristics. In preliminary analyses of subsamples of the Herschel
DEBRIS and DUNES surveys, Wyatt et al. (2012MNRAS.424.1206W 2012MNRAS.424.1206W) and
Marshall et al. (2014A&A...565A..15M 2014A&A...565A..15M) identified a tentative
correlation between debris and the presence of low-mass planets. Here
we use the cleanest possible sample out of these Herschel surveys to
assess the presence of such a correlation, discarding stars without
known ages, with ages <1Gyr, and with binary companions <100AU to rule
out possible correlations due to effects other than planet presence.
In our resulting subsample of 204 FGK stars, we do not find evidence
that debris disks are more common or more dusty around stars harboring
high-mass or low-mass planets compared to a control sample without
identified planets.
Description:
In this paper, we revisit the planet-debris disk correlation (or lack
thereof) in the Herschel DEBRIS and DUNES surveys (Eiroa et al.
2010A&A...518L.131E 2010A&A...518L.131E; 2013, J/A+A/555/A11; Matthews et al.
2010A&A...518L.135M 2010A&A...518L.135M; B. C. Matthews et al. 2015, in preparation) to
assess whether the frequency and properties of debris disks around a
control sample of stars are statistically different from those around
stars with high-mass or low-mass planets.

stars with significant detected emission have Sig>3.
Note (3): The 3σ upper limits are given for stars without significant
detected emission:
* for 0<SNR<3, the upper limit are calculated assuming the observed flux
is F100o+3σ

Note (4): Dust excess flux ratio, where F100dust=F100obs-F100star.
Note (5):
h = Note that this upper limit is based on the nondetection at 100um; this
star, however, has an excess emission at 8-35um with an inferred
fractional luminosity of Ld/L*=2x10-4 (Lisse et al. 2007ApJ...658..584L 2007ApJ...658..584L).

HIP 8102 (τ Cet), and HIP 98959.
Labels are defined in table 1 as:

3 = Subset from Set 1 harboring high-mass planets with masses >30M⊕
3a = for planets at >0.1AU
3b = for planets at 0.1AU
4 = Subset from Set 1 harboring low-mass planets with masses <30M⊕
